18th century? You're only off by 1,000 years. Those people are living in the 8th century. If anyone has ever thought the world and people have changed think again. The only thing that's changed about people is the technology. Not human nature.

The US should keep a constant force of predator drones armed with tank busting hellfire missiles circling overhead to take out every tank, armored vehicle and piece of artillery that comes anywhere near the kurds, assyrians or yazidi. After all, it was Obama;s stupidity that gave it to them. And we should supply them with all the arms, ammunition, RPG's and artillery they need. NOW is the time to nip this in the bud before those savages have a chance to metastacize.
